Abstract: The nutrition and health problems caused by unreasonable food systems are very prominent globally and have aroused wide concern. However, so far systematic evaluation of those problems is lacking. In this context, this paper systematically summarizes the evaluation methods for dietary nutrition and health effects of and the results of evaluation for Chinese and foreign residents, and proposes that changing dietary patterns, improving production technology and taking policy intervention actions are key to improve human nutrition and health. We expect this review to provide new ideas for systematic evaluation of dietary nutrition and health effects.
